Further, the vibration frequency of vibration source is 10～300Hz.
Described phase-change material is water or the aqueous solution or inorganic salts or organic matter.Described heat-transfer fluid is water or the aqueous solution or conduction oil.
Heat storage can is whole to adopt foundation bolt elasticity to be connected with pedestal.
When to adopt phase transition temperature be-30～45 ℃ low-temperature phase-change material, heat storage can and heat-transfer pipe material were polyethylene or metal, and the employing phase transition temperature is more than 60 ℃ during high temperature phase change material (pcm), and heat storage can and heat-transfer pipe material are metal.
The vibrating motor frequency of vibrator is 10～300Hz, generally based on power frequency, can adopt frequency modulator to regulate as required, and general heat storage can is at 1m
3Following vibrating motor power can adopt 0.5-1kW, 1-3m
3The heat storage can power of motor can adopt 0.5-3kW, 3m
3Above heat storage can power of motor can adopt more than the 3kW.The working time of vibrator can be according to the time set of phase transformation required time.
Under the effect of vibration source, heat storage can drives baffle plate and the vibration of heat accumulation ball, makes the heat transfer of phase-change material and heat transfer wall obtain reinforcement, reduces degree of supercooling, thereby has promoted the phase velocity of phase-change material in the heat storage can.
Described vibration source and heat storage can adopt and are rigidly connected, and vibrator can be arranged on the heat storage can bottom, also can be arranged on other positions of heat storage can and be connected with tank body.
Compared with prior art, advantage of the present utility model is: adopt the technology that the utility model adopted, can reduce heat accumulation process phase transformation degree of supercooling, accelerate transformation time 20～30%, it is about 10～20% to improve energy utilization rate, thereby has saved operating cost.
